Who is the mysterious "M"? According to the rubric, "M is Norman and Everyman - he is living memory, the eternal witness." In fact, he is the rather pretentious alter-ego of Edward Hillel, a Canadian artist who explores the secret life of cities. Hillel has worked in Germany, digging up traces of the Nazi past. For his first show in Britain he unearths Manchester's industrial guilty conscience. The focus of Hillel's enquiry is Little Ireland, a pocket of urban grot so appalling that it caught the attention of Engels and Marx. Now the area is being transformed into a suite of modish loft apartments.

The title of the exhibition, Coming Soon... , has been taken from the strap-line across the developer's hoardings. But the show might equally well be called Disappearing Fast. Hillel's subjects are the ghosts of the industrial past. His method is to interview the skeletons as they are being evicted from their closets.

Hillel presents his findings in a mixed-media assemblage of video, photography and scrap iron. Weird hunks of machinery, salvaged from the site, are mounted around the gallery on breeze-block plinths. One of them has a horrible old donkey jacket swinging above it. Elsewhere there are tobacco tins, pin-ups and other abandoned tokens of a workers' tea-break. Who knows where the owners of the teabags, the work boots and the pornography are now?

The video tour of the site highlights the surrealism of industrial machinery. Enormous green vats, encrusted in corroded pipework and incomprehensible dials, look as if they could have been dreamed up by Max Ernst rather than designed to fulfill a useful purpose. Hillel conducts an autopsy on the industrial monster, probing around its labyrinthine insides. Occasionally his camera catches a flash of a retreating shadow, like the sewer chase sequence from The Third Man. At other times it looks like something Piranesi would have come up with if he had had access to video equipment.
